Where these two actually differ
- We flag Dioxin and bleaching residues on the Aunt Flow and not on the Natracare.
- We flag Fragrance allergens (if scented variant) and Bacterial overgrowth from prolonged wear on the Natracare and not on the Aunt Flow.
- The gap is 30 points, wide enough that this is not a close call, and the Natracare is the one to buy.
- We are less certain about the Aunt Flow grade, at 75% confidence against 100%, because it discloses less.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
